[edit] class Controller
derived from: Actor
The Controller allows the User to control certain Actors with mouse and keyboard through states. It also controls when to start or to stop a scene and manages the node trees in a scene. The Controller can "possess" actors and will use the possessed actors' position and rotation as the viewport camera.
[edit] Members:
[edit] static bool bRunning
Static variable that determines is the scene is running or not. Can be accessed from everywhere.
[edit] static vector <Node *> nodeList
A list of all the nodes in the scene.
[edit] static vector<Node *> nodeTree
A list of all the node Trees starting Nodes in the scene. Node tree starting nodes (Root Nodes) are RootNode and KeyInputNode.
[edit] Actor *controlledActor
The Actor this controller is currently controlling - also serves as the viewLocation for the Renderer.
[edit] NavButton *navBtn
A reference to the navigation button, used for view Rotation.
[edit] Vector3f lookPoint
A point that is 1 unit away from the controlledactor's location in the direction of the controlledactor's rotation. Is used for viewport.
[edit] int state
Can be either MOVECURSORSTATE or MOVECAMERASTATE, defines if we change the viewpoint with mouse/keyboard or just move the cursor around.
[edit] int moveMode
Can be FLYINGCAMERA or WALKINGCAMERA. Currently only supports FLYINGCAMERA.
[edit] Actor * cameraActor
The viewport position reference. Also the Actor that gets moved when in MOVECAMERASTATE.
[edit] Functions:
[edit] void update(double deltaTime)
called from: Renderer::update() (as part of ActorList)
checks the state variable and calls processMove if we're in MOVECAMERASTATE. Also calls updateNodes() if the scene is running (bRunning is true).
[edit] void processMove (double deltaTime)
called from: Controller::update(double deltaTime)
This function takes mouse movement and keyPresses from NavBtn and Input and changes the controlledActor's location, rotation and calculates the lookPoint location.
